▎ 摘　　要

NOVELTY - Activating the active lithium in the positive pre-lithiated cell comprises applying a high voltage to the battery cell during the process of preparing the capacity of the battery cell and activating the active lithium, where the high voltage is 4.2-4.5 V. The anode material layer of the anode sheet of the positive pre-lithiated battery cell contains an anode lithium replenishing agent. The anode lithium replenishing agent contains active lithium. USE - The method is useful for activating the active lithium in the positive pre-lithiated cell. ADVANTAGE - The method: has no influence on the cell interface and battery performance after capacity, and can avoid the risk of gas production under high temperature and high pressure when active lithium is activated in the conventional formation stage. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a pre-lithiated battery cell prepared by the above method.
